Definitions

  • the invention relates to a roller apparatus for sliding doors mounted thereon, in particular with suspension bearings, with a chassis having at least one roller, with a threaded bolt fixedly arranged on the chassis, with a support device for the sliding door, which is vertically adjustable on the threaded bolt, a socket with a corresponding one on the threaded bolt Internal thread is mounted, which is rotatable relative to the threaded bolt and with respect to the support device, and with a bearing arranged between the bushing and the support device, via which the support device and the bushing are held together by positive locking.
  • Sliding doors are known and are used, for example, to divide rooms. They can consist of several plate-shaped sliding elements that lie in a row next to each other when the sliding door is closed.
  • the wings are moved on a special rail system in such a way that in the parking position they are stacked parallel to one another in a wall niche and form a package.
  • a corresponding rail system is provided, which runs on the ceiling and / or on the floor. If the rails are only arranged on the ceiling, the sashes are suspended from them on corresponding trolleys and can be moved by means of them.
  • a trolley for suspended sliding doors of the type mentioned is known from DE-OS 29 49 539.
  • the trolley consists of a chassis on which a roller is rotatably mounted, so that the chassis can be moved along a corresponding rail.
  • a threaded bolt with an adjoining pin is fixedly arranged on the underside of this chassis. This vertically downwardly projecting threaded bolt with the pin protrudes through a top opening in a support device for the sliding door.
  • the carrying device has a lateral opening for receiving a so-called adjusting drum with an internally threaded bore.
  • the adjusting drum is rotatably mounted on the threaded bolt of the chassis, so that when the adjusting drum is rotated, the height of the carrying device and thus the sliding door is reached.
  • a disadvantage of this known rolling device is that the sliding door rests with its entire weight on the adjusting drum via its supporting device, so that when the adjusting drum is rotated there is a very high frictional resistance between the latter and the supporting device. As a result, the height adjustment of the sliding door is very difficult and therefore not very user-friendly, which also affects the setting accuracy.
  • a further disadvantage of the known roller apparatus is that if the sliding door is adjusted carelessly, the adjusting drum can come out of the threaded bolt and the sliding door thus falls down.
  • This trolley is also provided with a threaded bolt fixed to the chassis and with a height-adjustable support for the sliding door on the threaded bolt, a bushing having a corresponding internal thread being mounted on the threaded bolt.
  • the upper end face of the bush is supported on the lower end face of a support ring screwed into the support device.
  • the entire weight of the support device rests on this support ring, so that large frictional resistances occur when the bushing is rotated via a worm drive. This also makes the height adjustment of this sliding door relatively stiff and not very user-friendly.
  • the invention relates to a trolley of the type specified in the preamble of claim 1.
  • a trolley is known from DE-C-598 356. Proceeding from this, the object of the invention is to further develop the known roller apparatus in such a way that the height adjustment device is easier to operate.
  • the frame has at least one roller, that the bearing is designed as a roller bearing or as a ball bearing, which consists of an inner bush formed by the bushing and an outer ring fixed to the support device, between which rolling elements or balls are arranged, and that to form the positive connection, the outer ring is provided with a radially inwardly projecting in the direction of the bushing inner ring, by means of which the support device is supported via the rolling elements or balls on a radial ring of the bushing.
  • the bearing is designed as a roller bearing or as a ball bearing, which consists of an inner bush formed by the bushing and an outer ring fixed to the support device, between which rolling elements or balls are arranged, and that to form the positive connection, the outer ring is provided with a radially inwardly projecting in the direction of the bushing inner ring, by means of which the support device is supported via the rolling elements or balls on a radial ring of the bushing.
  • a trained according to this technical teaching trolley has the essential advantage that the roller bearing arranged between the bushing and the support device in the manner according to the invention allows the bushing to be rotated and thus the height adjustment of the support device for the sliding door is made possible with a minimal effort, so that a simple height adjustment, which also has a positive effect on the accuracy of the height adjustment, is realized in terms of effort and thus ease of use.
  • the construction of the rolling bearing according to the invention realizes a structurally very simple rolling bearing, wherein the form-fit ensures very simple installation without the need for additional fastening means.
  • the interlocking of the parts by positive locking is achieved by corresponding projections so that the rolling elements of the rolling bearing rest on the inner bush, the outer ring on the rolling elements and finally the support device on the outer ring.
  • a snap ring is preferably provided to secure the parts.
  • a ring can also be arranged between this snap ring and the roller bearing, which serves for stability. But it can also be designed to be elastic so that axial and radial forces can be absorbed.
  • a lock nut is provided for securing the bush on the threaded bolt, preferably with a clamping washer interposed.
  • the threaded bolt has a radially projecting stop element at its free end and that the bushing has an inner bore corresponding to the stop element and correspondingly stepped to the internal thread. This prevents the threaded bolt from being accidentally unscrewed from the socket when adjusting the sliding door.
  • the stop element is a stop disc.
  • a stop washer can be arranged on the threaded bolt in a technically simple manner and fulfills the function of a stop element in a technically safe manner, so that the threaded bolt is prevented from escaping from the bushing.
  • the stop element can preferably be screwed or riveted to the threaded bolt.
  • the trolley 1 consists of a chassis 2. On this a roller 3 is freely rotatable about a horizontal axis.
  • the roller apparatus 1 can be moved on a rail 4 within a hollow box section 5 by means of this roller 3 of the chassis 2. This can be seen in FIG. 3.
  • a sliding door 6 is indicated by dash-dotted lines in this FIG. 3, which hangs on the rolling device 1 and should be movable along the rail 4 by means of the latter.
  • a threaded bolt 7 is screwed vertically downward on the underside of the chassis 2. This has at its free end a stop element 8 in the form of a stop disc which is fastened to the threaded bolt 7 by means of a corresponding screw 9.
  • the threaded bolt 7 of the chassis 2 serves to accommodate and adjust the height of a support device 10 for the sliding door 6.
  • the support device 10 is designed as an aluminum housing which has two clamping screws 11.
  • a ball bearing 12 is arranged between the support device 10 and the threaded bolt 7 for height adjustment.
  • This ball bearing 12 initially consists of a bushing 13 in the form of an inner bushing.
  • This socket 13 has an internal thread 14 in the upper region, by means of which the socket 13 is rotatably mounted on the threaded bolt 7 and is adjustable in height.
  • an internal bore 15 adjoins the internal thread 14, the internal diameter of which is larger than the internal diameter of the internal thread 14, so that a step 16 is formed in the transition region between the internal thread 14 and the internal bore 15. This forms the counterpart to the stop element 8 of the threaded bolt 7.
  • the ball bearing 12 also has an outer ring 17 on the outside, which is fixedly connected to the carrying device 10.
  • the balls 18 of the ball bearing 12 are arranged between the inner bush 13 and the outer ring 17.
  • the bushing 13 initially has a radial ring 19 on the underside, on which a lower row of balls 18 rests.
  • An upper row of balls 18 rests on the upper side on the inner ring 20 of the outer ring 17.
  • the support device 10 also has an inner ring 21, by means of which the support device 10 rests on the outer ring 17.
  • a ring 22 is arranged between the inner ring 21 of the carrying device 10 and the bush 13. Secured are the parts by a snap ring 23 on the socket 13.
  • a lock nut 24 on the threaded bolt 7 serves to secure the carrying device 10 on the threaded bolt 7 against unintentional height adjustment, with a clamping disk 25 being arranged therebetween.
  • the height adjustment of the trolley 1 works as follows:
  • Fig. 1 the starting position is shown, that is, the support device 10 with the sliding door 6 in the highest position.
  • the height adjustability is limited by the stop element 8 when it has reached level 16.
  • This end position is shown in FIG. 2, the dimension h for the height adjustability being indicated in this illustration.
  • the lock nut 24 is tightened again, thus securing the position of the sliding door 6.
  • the ball bearing 12 of the trolley 1 can absorb axial and radial forces.
  • the trolley 1 is characterized by its flat design despite the possibility of height adjustment.
  • the sliding door 6 is suspended on the trolley 1.
  • the trolley 1 with its parts essential to the invention can be used so that it can be moved on the floor and the Sliding door 6 rests on it.
  • a corresponding height adjustability is also made possible here by the mechanism according to the invention.
